View Full Version : [ubuntu] Error: Upgrade from 10.10 Maverick to 11.04 Natty

February 1st, 2011, 08:21 AM

I browsed on internet to find how to upgrade to 11.04 and find the answer.

Press Alt+F2 and enter the command update-manager -d

After authentication, the manager showed the updates and at some point of time, I got the following error.

E: Encountered a section with no Package: header
E: Problem with MergeList /var/lib/apt/lists/in.archive.ubuntu.com_ubuntu_dists_natty_universe_ binary-i386_Packages
E: The package lists or status file could not be parsed or opened.
E: _cache->open() failed, please report.

Everytime I open Update Manager/Synaptic Package Manager, the following error encounters. Please help me in this regard.

I doubted its problem of sources.list file. I uploaded a copy of the file.

This is only what can be expected from a system in alpha.

Best is to search for advice in this forum:
